DETAILED DESCRIPTION

Referring generally to the figures, various embodiments of a hard hat are shown. As will be understood, hard hats are worn by users during activities where the user is frequently moving. Applicant has developed various mechanisms to securely and comfortably couple hard hats to the user's head even while the user works, moves around and speaks.

Applicant has developed hard hat securing mechanisms provide several that provide several advantages and improvements compared to previous designs. First, the hard hat securing mechanisms permit various aspects of the securing mechanisms, such as the back strap behind the user's head, to pivot towards more comfortable positions without requiring manual adjustment from the user. Second, the hard hat securing mechanisms provide improved coupling mechanism location between various straps to provide increased stability and comfort for the user. Third, the hard hat securing mechanisms are adjustable to a wide range of head sizes.

Applicant has developed hard hat systems configured to be comfortably worn by people with varying head sizes. For example, the hard hat includes a strap system with receivers and clips that are configured to rotate with respect to each other when the strap system is coupled to a hard hat on a user. Applicant has observed that allowing the straps to rotate at the location of coupling permits a more comfortable repositioning of the straps relative to the head of the user as compared to hard hat systems in which the straps are coupled via receivers and clips that do not rotate with respect to each other.

Referring to FIGS. 1-8, a perspective view of a hard hat 10 is shown according to an exemplary embodiment. As will be described, in various embodiments the hard hat 10 includes an outer shell, a suspension system, a strap system, a clip, and a receiver to couple the strap system to the coupling system and/or the hard hat. Hard hat 10 includes an outer shell 20 formed from a rigid material, such as a rigid polymer material. Hard hat 10 includes an impact protection layer 40 supported within outer shell 20. Details of the various embodiments of impact protection layer 40 and support within outer shell 20 are discussed in more detail below. Hard hat 10 includes a suspension system, shown as crown 12, and a strap system 14 to support and secure hard hat 10 to a user's head.

Outer shell 20 includes an external surface 21 and an opposing internal surface 23 that defines a cavity 25 of outer shell 20. Outer shell 20 defines a plurality of venting apertures 22 and impact protection layer 40 defines a plurality of corresponding apertures 42. Apertures 22 and 42 collectively provide fluid communication between cavity 25 and ambient air proximate to external surface 21 of outer shell 20. Front brim 24 of outer shell 20 projects outwardly from a front 16 of outer shell 20.

Outer shell 20 includes recess 26 positioned between front 16 and rear 18 of outer shell 20, proximate the ears of a user wearing hard hat 10. In a specific embodiment recess 26 extends height 28 above lower surface outer shell 20 in front of recess 26.

Outer shell includes coupling components 36 that couple outer shell 20 to crown 12. Outer shell 20 includes apertures 30 proximate recess 26. Apertures 30 are configured to receive coupling mechanisms, such as clips, which may be used to couple objects to outer shell 20. Outer shell 20 includes apertures 32 to which strap system 14 can be coupled. As will be described in more detail below, strap system 14 secures outer shell 20 to a user's head.

Turning to FIGS. 5-8, various aspects of impact protection layer 40 and outer shell 20 are shown. Impact protection layer 40 is coupled to internal surface 23 of outer shell 20. Outer shell 20 includes a plurality of protrusions, shown as ribs 34, that extend towards cavity 25. A plurality of channels 38 are defined between ribs 34, such that one or more channels 38 are defined by at least two ribs 34.

Impact protection layer 40 includes apertures 42 that provide fluid communication between cavity 25 and outer shell 20. Impact protection layer 40 includes a plurality of recesses 44 that receive ribs 34 of outer shell 20. When impact protection layer 40 is coupled to outer shell 20, protrusions 46 project into channels 38 of outer shell 20. In a specific embodiment an adhesive is applied between protrusions 46 and channels 38 to couple impact protection layer 40 to outer shell 20. Ribs 34 retain the adhesive within channel 38, reducing the chances of adhesive extruding out of channel 38 and becoming visible and/or interfering with the fluid communication provided by apertures 42 and apertures 22. This method of securing impact protection layer 40 to outer shell 20 permits an easier method of manufacture compared to over molding the outer shell 20 around the impact protection layer 40.

In a specific embodiment the adhesive is a liquid adhesive. In a specific embodiment the impact protection layer 40 includes an expanded polystyrene (EPS) foam.

Impact protection layer 40 includes a plurality of recesses 50. When impact protection layer 40 is coupled to outer shell 20, recesses 50 provide fluid communication between one or more apertures 42 of impact protection layer 40.

Turning to FIGS. 9-10, outer shell 20 includes coupling mechanisms, shown as front clips 52 and back clips 54. Front clips 52 and back clips 54 couple outer shell 20 to strap system 14, as described in more detail below.

Turning to FIGS. 11-13, various aspects of outer shell 80 are shown. Outer shell 80 is functionally similar to outer shell 20 except for the differences described herein. Outer shell 80 includes various connection points to adjustably couple strap system 14 to outer shell 80. Front clips 52 couple strap system 14 to a front-side portion of outer shell 80 proximate the user's temple. Back clips 54 couple strap system 14 to a rear portion of outer shell 80.

Outer shell 80 includes multiple connection points 56 and 58 to couple to back clips 54. Upper connection points 58 are height 60 higher than lower connection points 56. In a specific embodiment, height 60 is between 0.5 inches and 3 inches, and more specifically between 0.75 inches and 2 inches, and more specifically height 60 is 1 inch.

When back clips 54 are coupled to upper connection points 58, back straps of strap system 14 are pulled tighter against a user's head. This provides a more secure fit for users, which can be more comfortable for users with smaller heads. When back clips 54 are coupled to lower connection points 56, back straps of strap system 14 are permitted more slack. A silhouette of back strap 59 is depicted in FIG. 12 when back clip 54 is coupled to upper connection point 58. This provides a looser fit for users, which can be more comfortable for users with larger heads. In a specific embodiment upper connection points 58 are circumferentially closer to each other than lower connection points 56 (e.g., upper connection points 58 are inboard compared lower connection points 56).

Turning to FIG. 14, various aspects of a suspension system, shown as crown 100, are shown. Hard hat 10 is configured to accommodate various sizes of users' heads. For exemplary purposes only, hard hat 10 is configurable to securely couple to a head diameter 64 of 6.63″ (20.8″ circumference), a head diameter 66 of 7.48″ (23.5″ circumference), and a head diameter 68 of 8.5″ (26.69″ circumference), which is approximately the diameter of a head with diameter 66 with a surrounding piece of head gear, such as a hat, hoodie, or bandana.

Turning to FIGS. 15-22, various aspects of crown 100 are shown. Crown 100 is functionally similar to crown 12 except for the differences described and depicted herein. Crown 100 is configured to couple to safety headwear and a head of a person wearing the safety headwear. Arms 104 of crown 100 couple crown 100 to outer shell, such as at coupling components 36 of outer shell 20. Upper band 106 of crown 100 is fixedly coupled to outer shell 20 via arms 104. Front band 118 of upper band 106 circumferentially surrounds a front a user's head, thereby helping secure crown 100 to the user's head.

Middle frame 108 is pivotably coupled to upper band 106 and pivots with respect upper band 106 around axis 110. The positioning of axis 110 between middle frame 108 and upper band 106 closer to the back of the user's head (compared to other designs) permits easier rotation of crown 100 with respect to the user's head as the user's head moves.

Middle frame 108 defines apertures 114, which couple to securing component, shown as ratchets 112. Ratchets 112 can be loosened with respect to middle frame 108 to permit middle frame 108 to be adjusted to the shape of a user's head. When the adjustment has been made to conform to the user's head, ratchets 112 can be tightened to fixedly couple upper band 106 to middle frame 108 such that upper band 106 no longer pivots with respect to middle frame 108. If further adjustments need to be made, then ratchets 112 can once again be selectively loosened and tightened.

Adjustable band 120 is coupled to middle frame 108 and pivots with respect to middle frame 108 about axis 116. The pivotable coupling between adjustable band 120 and middle frame 108 contributes to user comfort by permitting adjustable band 120 to more easily alter its position and/or configuration as the user is moving around. For example, if the user pivots his head back to look straight up, the back of the user's neck will correspondingly arch backwards. When the user's neck is in that configuration, adjustable band 120 pivots downwards with respect to middle frame 108 to match the contours of the user's neck, thereby avoiding and/or mitigating the adjustable band 120 digging into the user's neck and negatively affecting the user's comfort.

Adjustable band 120 includes first arm 122, which is coupled to middle frame 108, and second arm 124, which is also coupled to middle frame 108. First arm 122 and second arm 124 can be adjusted with respect to body 146 of adjustable band 120, thereby extending or retracting the overall length of adjustable band 120 along arcuate axis 154. A user can adjust the positioning of first arm 122 and second arm 124 with respect to body 146 by actuating an interface, shown as button 140. As shown in FIGS. 16 and 17, crown 100 is at or near a minimum adjustable circumference 152 and/or diameter 150. To adjust circumference 152 and/or diameter 150 of crown 100, a user presses button 140. When button 140 is pressed, first arm 122 and second arm 124 can be either extended or retracted along arcuate axis 154 with respect to body 146, thereby lengthening or shortening adjustable band 120.

Turning to FIGS. 18-19 in particular, first arm 122 includes aperture 126, which includes teeth 128. Teeth 128 of first arm 122 interface with a protrusion, such as teeth, of body 146. First end 130 of first arm 122 is coupled to middle frame 108. Second end 134 of first arm 122 is opposite first arm 122. First end 130 defines aperture 132, at the center of which is axis 116. When first arm 122 is extended distance 136, teeth of body 146 engage at or near the left-most tooth in FIG. 19. When first arm 122 is retracted to distance 138, teeth of body 146 engage at or near the right-most tooth in FIG. 19. In a specific embodiment, distance 136 is 145 mm and distance 138 is 65 mm. In various embodiment second arm 124 has a similar and symmetrical configuration and functionality as first arm 122.

Turning to FIGS. 20-22, depicted is crown 100 in a slightly extended configuration with respect to FIGS. 15-17. In the configuration in FIGS. 20-22, button 140 has been actuated and first arm 122 has been slightly extended with respect to body 146.

Turning to FIGS. 23-85, various designs for strap systems are shown. In various embodiments the strap systems designed are sized for users with larger heads and/or users with headgear, and functionality is provided to shorten the length of strap systems by users with smaller heads as necessary.

Turning to FIGS. 23-26, various aspects of strap system 200 are shown. Strap system 200 is substantially similar to strap system 14 and other strap systems described herein, except as otherwise described and depicted. In various embodiments, strap system 200 is configured to couple a suspension system, such as crown 100, to a head of a person, and thus also couple safety headwear to the head of a person. In various embodiments, strap system 200 is configured to couple safety headwear to a head of a person. Strap system 200 includes side straps 202, which couple to outer shell 20 via side clips 210 at or near a front-side of a user, such as near the user's temple. Back straps 204 couple to outer shell 20 via back clips 212 at or near a back of the user's head. In use, as a user pulls down on chin strap 206, ratchet 166 of adjustable band 160 rotates with respect to the user's head to the configuration shown in FIG. 23. In a specific embodiment, strap system 200 includes a first strap, such as side strap 202 or a back strap 204, that couples to a clip (e.g., clip 546 shown in FIGS. 78-81). In a specific embodiment, side strap 202 is positionable below a chin of a user of a hard hat when a clip coupled to the strap and a receiver coupled to the hard hat are coupled together.

Chin strap 206 extends underneath a front portion of user's face, such as underneath the user's chin. Side straps 202, back straps 204, and chin strap 206, are coupled together via coupler 208. In a specific embodiment, chin strap 206 includes adjustor 218, which can be actuated by a user to extend or retract a total distance of chin strap 206, thereby adjusting the position of coupler 208 with respect to outer shell 20 and the user's face. In a specific embodiment, coupler 208 permits chin strap 206 to rotate with respect to coupler 208 (similar to the functionality of clip 546, shown in FIGS. 78-81 and described below), thereby facilitating the chin strap 206 maintaining a more flush and therefore more comfortable configuration with respect to the user's neck.

In various embodiments back straps 204 extend through cavity 164 of adjustable band 160. Adjustable band 160 is substantially similar to adjustable band 120, except as shown and depicted herein. Ratchet 166 of adjustable band 160 permits the user to adjust the position of first and second arms of adjustable band 160 with respect to the body, thereby extending or retracting the length of adjustable band 160.

Extending back straps 204 through cavity 164 of adjustable band 160 provides several advantages. First, extending back straps 204 through cavity 164 facilitates managing the strap system 200 while donning or removing the helmet (e.g., the straps are less likely to be tangled or knotted because the straps are biased towards a perimeter of the hard hat). Second, extending back straps 204 through cavity 164 secures pad 162 against the user's head while the hard hat is being worn. Third, extending back straps 204 through cavity 164 routs the straps further from the user's ears compared to other designs, thereby increasing the user's comfort.

Adjustable band 160 includes pad 162, which interfaces against the back of the user's head and neck area. In a specific embodiment, pad 162 is a single piece, rather than a series of different pads.

Turning to FIGS. 27-29, various aspects of strap system 220 are shown. Strap system 220 is substantially similar to strap system 14 and other strap systems described herein, except as otherwise described and depicted. Ladder lock clip 222 couples back strap 204 to a rear portion of outer shell 20. Ladder lock clip 222 includes aperture 224, which is bisected by bar 226. In use, end 205 of back strap 204 is inserted in direction 228 through aperture 224 above bar 226, and then inserted through aperture 224 in direction 230. This interface between back strap 204 and ladder lock clip 222 permits back strap 204 to be extended or retracted, thereby lengthening or shortening the distance of back strap 204 between coupler 208 and outer shell 20. An advantage of the design of strap systems 220 is that there is a larger range of lengths that strap system 220 can be adjusted to, compared to some other designs.

Turning to FIGS. 30-32, various aspects of strap system 240 are shown. Strap system 240 is substantially similar to strap system 14 and other strap systems described herein, except as otherwise described and depicted. Ladder lock clip 242 is substantially similar to ladder lock clip 222 except as otherwise described and depicted herein. Side strap 202 is coupled to ladder lock clip 242, and subsequently end 203 of side strap 202 is extended through band 244. Band 244 positions side strap 202 against itself, thereby securing side strap 202 from being inadvertently adjusted with respect to ladder lock clip 242. Advantages of the design of strap systems 240 are that there is a larger range of lengths that strap system 220 can be adjusted to, compared to some other designs, and that the user can relatively easily adjust the length side strap 202.

Turning to FIGS. 33-34, various aspects of strap system 260 are shown. Strap system 260 is substantially similar to strap system 14 and other strap systems described herein, except as otherwise described and depicted. Back clip 262 secures supplemental back strap 264 to outer shell 20. Back strap 266, which extends from coupler 208, is coupled at aperture 268 to a coupling mechanism, shown as cam 270. By actuating cam 270, a user can either extend or retract the total distance of back strap 266 and supplemental back strap 264 between outer shell 20 and coupler 208.

Turning to FIGS. 35-38, various aspects of strap system 280 are shown. Strap system 280 is substantially similar to strap system 14 and other strap systems described herein, except as otherwise described and depicted. Back clip 294 couples back strap 282 to at or near a rear portion of outer shell 20. Back strap 282 includes a first aperture 286, proximate end 284, and a second aperture 290, which is distance 292 from end 284. To extend or retract the distance of back strap 282, a user selectively couples back clip 294 to either first aperture 286 or second aperture 290. In use, a user extends coupling mechanism, shown as removable rod 288 through aperture 296 of back clip 294. Removable rod 288 is also extended through at least one of first aperture 286 or second aperture 290. If the user desires a longer length of back strap 282, the user extends rod 288 through first aperture 286 (best shown FIG. 37). If the user desires making the length of back strap 282 shorter, the user extends rod 288 through second aperture 290 (best shown FIG. 238). An advantage of the design of strap systems 280 is that the straps will not creep or slide because the selectable adjustment lengths are fixed.

Turning to FIGS. 39-41, various aspects of strap system 300 are shown. Strap system 300 is substantially similar to strap system 14 and other strap systems described herein, except as otherwise described and depicted. Back clip 302 is substantially similar to back clip 294, except for the differences described and depicted herein. Back clip 302 includes pivotable arm 306, which together with body 304 of back clip 302 selectively enclose cavity 308. Aperture 312 of back strap 310 is positioned within cavity 308. A user adjusts a usable length of back strap 310 by selecting which aperture 312 of back strap to couple to back clip 302.

Turning to FIGS. 42-45, various aspects of strap system 320 are shown. Strap system 320 is substantially similar to strap system 14 and other strap systems described herein, except as otherwise described and depicted. Back clip 322 couples supplemental back strap 324 to a rear portion of outer shell 20. Coupling mechanism, shown as clip 328, couples supplemental back strap 324 to back strap 326. Back strap 326 is substantially similar to back strap 282. Clip 328 includes a cavity 330 into which a portion of back strap 326 is inserted. In use, lower arm 332 of clip 328 is inserted into one or more apertures of back strap 326. To adjust the total distance of supplemental back strap 324 and back strap 326 between outer shell 20 and coupler 208, the user changes which aperture of back strap 326 is coupled to clip 328.

Turning to FIGS. 46-49, various aspects of strap system 340 are shown. Strap system 340 is substantially similar to strap system 14 and other strap systems described herein, except as otherwise described and depicted. Clip 342 couples back strap 344 to outer shell 20. Back strap 344 is substantially similar to back strap 282, except for the differences described and depicted herein. Clip 342 includes at least one arm 346, into which an aperture of back strap 344 is inserted. In a specific embodiment clip 342 includes two arms 346, which define a gap 348 between them. Back strap 344 is inserted through gap 348 into cavity 350, and one or more of apertures of back strap 344 is extended around arms 346, thereby securing strap 344 to arms 346.

Turning to FIGS. 50-52, various aspects of strap system 360 are shown. Strap system 360 is substantially similar to strap system 14 and other strap systems described herein, except as otherwise described and depicted. Side strap 362 extends through the clip coupled to outer shell 20, thereby defining loop 364. An end of side strap 362 is coupled to a coupling mechanism, shown as sliding clip 366. To adjust a distance of side strap 362 between coupler 208 and outer shell 20, sliding clip 366 is actuated either closer or further from outer shell 20, thereby decreasing or increasing the size of loop 364, respectively.

Turning to FIG. 53, various aspects of strap system 380 are shown. Strap system 380 is substantially similar to strap system 14 and other strap systems described herein, except as otherwise described and depicted. Side straps 382 include gradations at periodic locations to facilitate symmetrical and/or consistent user adjustments of side straps 182. In use, a user can look at the positioning of the side strap 382 on the left side of his face with respect to the gradations, and configure the other side strap 382 to the same or a similar positioning. This provides the user an efficient way to symmetrically configure the outer shell on the user's head. Back straps 384 also include gradations providing a similar mechanism to facilitate user adjustments.

Turning to FIGS. 54-58, various aspects of strap system 400 are shown. Strap system 400 is substantially similar to strap system 14 and other strap systems described herein, except as otherwise described and depicted. Strap system 400 is coupled to shell 20 via front clip 402 and rear clip 406. Front clip 402 has a diameter that is different than diameter 408 of rear clip 406. The different diameters/shapes of front clip 402 and rear clip 406 help the user quickly identify if the user is attempting to insert front clip 402 or rear clip 406 into an incorrect location on outer shell 20 (e.g., by trying to insert front clip 402 into the location where rear clip 406 is inserted).

Chin strap 206 of strap system 400 includes a buckle 410 that is configured at or near coupler 208 on one side of user's face (shown in FIG. 58). This positioning of buckle 410 improves the user experience by reducing the chaffing of the buckle 410 against the user's head when the user is talking and/or moving (e.g., as compared to if the buckle 410 is proximate the user's throat). Additionally, the side positioning of buckle (shown in FIG. 58) improves the ability of the user to see the buckle and confirm they are orienting the buckle as desired, it is easier for the user to access a buckle on the side as compared to locating the buckle under the user's chin, and the side-positioning of buckle 410 permits increased length adjustments of the chin strap 206 compared to other designs.

Turning to FIGS. 59-61, various aspects of strap system 420 are shown. Strap system 420 is substantially similar to strap system 14 and other strap systems described herein, except as otherwise described and depicted. Clip 422 permits the adjustment of side strap 430 by wrapping side strap 430 around clip 422 before inserting clip into outer shell 20. Clip 422 includes side arms 424, which couple clip 422 to outer shell 20. In a first configuration, side strap 430 extends from clip 422 without wrapping around center arm 426, thereby providing a relatively longer length of side strap (shown in FIG. 60). In a second configuration, side strap 430 is wrapped around center arm 426, thereby shortening the length of side strap 430 by two times height 428 of center arm 426 (shown in FIG. 61) (“two times” because side strap 430 needs to both extend up to the top of center arm 426 and transit that same distance down to the bottom of clip 422). In use, users shorten side strap 430 by wrapping side strap 430 around center arm 426. Alternatively, users lengthen side strap 430 by unwrapping side strap 430 from center arm 426. An advantage of the design of strap systems 420 is that the straps will not slide because the strap length adjustment is a fixed length. Another advantage is that no special tooling or dexterity is required to adjust the strap length.

Turning to FIGS. 62-66, various aspects of strap system 440 are shown. Strap system 440 is substantially similar to strap system 14 and other strap systems described herein, except as otherwise described and depicted. Clip 442 is substantially similar to clip 422 except for the differences described and depicted herein. Clip 442 is coupled to a receiver in shell 20, either with the strap wrapped around the center arm (FIG. 65), or without the strap wrapped around the center arm (FIG. 63).

Turning to FIGS. 67-75, various aspects of strap system 460 are shown. Strap system 460 is substantially similar to strap system 14 and other strap systems described herein, except as otherwise described and depicted. Clip 462 includes side arms 464, which selectively couple with apertures 472 of receiver 470. Protrusions, shown as vertical ribs 466, extend from side arms 464. When clip 462 is coupled to receiver 470, teeth 468 engage with receiver to maintain the position of clip 462. FIGS. 71-75 depict clip 462 being manipulated to couple and decouple clip 462 with receiver 470.

Turning to FIG. 76, various aspects of strap system 500 are shown. Strap system 500 is substantially similar to strap system 14 and other strap systems described herein, except as otherwise described and depicted. Clip 504 couples with receiver 502. In various embodiments, receiver 502 is molded into the outer shell of the hard hat.

Turning to FIG. 77, various aspects of strap system 520 are shown. Strap system 520 is substantially similar to strap system 14 and other strap systems described herein, except as otherwise described and depicted. Clip 522 is substantially similar to clip 422, except as otherwise described and depicted herein. A user can selectively wrap or unwrap strap 524 around center arm of clip 522 to shorten or length the length of strap 524.

Turning to FIGS. 78-81, various aspects of strap system 540 are shown. Strap system 540 is substantially similar to strap system 14 and other strap systems described herein, except as otherwise described and depicted. Strap system 540 includes clip 546 and receiver 542 Clip 546 couples with receiver 542. Receiver 542 is configured to mechanically and reversibly couple and decouple to clip 546. Clip 546 is released by receiver 542 as a result of a user actuating coupling mechanism, such as a circular element, shown as release button 552. Button 552 of clip 546 interfaces with receiver 542 when clip 546 rotates with respect to receiver 542. In a specific embodiment, housing 545 of receiver 542 peripherally surrounds button 552 when clip 546 is coupled to receiver 542. In a specific embodiment, housing 545 of receiver 542 includes an opening 531, and the button 552 extends through opening 531 such that housing 545 peripherally surrounds button 552. Receiver 542 couples to a strap or other object (e.g., safety headwear, such as being rigidly coupled to safety headwear) via coupler 544, and clip 546 couples to a strap or other object via coupler 548. When clip 546 and receiver 542 are coupled together, clip 546 rotates with respect to receiver 542 about axis 550. In a specific embodiment, release button 552 faces towards the user's head. In various embodiments, button 552 actuates to decouple clip 546 from receiver 542. In various embodiments, strap 557 extends from clip 546 and button 552 actuates along axis 550, which is perpendicular to strap-receiving element 559.

Clip 546 rotates with respect to receiver 542 over range 554. In a specific embodiment, range 554 is between 60 degrees and 150 degrees, and more specifically between 90 degrees and 135 degrees, and more specifically is 120 degrees. In a specific embodiment, range 554 is at least 60 degrees, and more specifically is at least 90 degrees, and more specifically is at least 120 degrees. The pivotable range 554 of clip 546 with respect to receiver 542 improves the ability of straps to reposition as needed while the user is moving and working.

Receiver 542 defines a longitudinal axis 543, and clip 546 defines a longitudinal axis 547. In various embodiments, receiver 542 rotates over range 555 (e.g., at least 30 degrees, at least 45 degrees, at least 60 degrees) with respect to clip 546 in a first rotational direction from a starting position of the first longitudinal axis and the second longitudinal axis being aligned (see FIG. 80). In various embodiments, receiver 542 rotates over range 556 (e.g., at least 30 degrees, at least 45 degrees, at least 60 degrees) with respect to clip 546 in a second rotational direction, opposite the first rotational direction, from a starting position of the first longitudinal axis and the second longitudinal axis being aligned (see FIG. 80).

In various embodiments, receiver 542 is rotatably coupled to clip 546 allowing rotation in a first rotational direction 533 such that longitudinal axis 547 of clip 546 is able to form at least a 30 degree angle relative to longitudinal axis 543 of receiver 542, and more specifically at least a 45 degree angle, and more specifically at least a 60 degree angle, and more specifically at least a 90 degree angle. In various embodiments, receiver 542 is rotatably coupled to clip 546 allowing rotation in a second rotational direction 535 opposite the first rotational direction 533 such that the longitudinal axis 547 of clip 546 is able to form at least a 30 degree angle relative to the longitudinal axis 543 of receiver 542, and more specifically at least a 45 degree angle, and more specifically at least a 60 degree angle. In various embodiments, receiver 542 is rotatably coupled to clip 546 restricting rotation in a second rotational direction 535 opposite the first rotational direction 533 such that the longitudinal axis 547 of clip 546 forms an angle no more than 5 degrees relative to the longitudinal axis 543 of receiver 542.

In various embodiments, receiver 542 has a more limited rotational range with respect to clip 546. In particular, receiver 542 rotates over range 556 (e.g., less than 5 degrees, less than 1 degree) with respect to clip 546 in the second rotational direction, opposite the first rotational direction, from a starting position of the first longitudinal axis and the second longitudinal axis being aligned (see FIG. 80).

In a specific embodiment, receiver 542 defines a longitudinal axis 543, clip 546 defines a longitudinal axis 547, and button 552 actuates along an axis 543 perpendicular to the first and second longitudinal axes 543, 547 to decouple the clip 546 from the receiver 542.

Turning to FIGS. 82-85, various aspects of strap system 560 are shown. Strap system 560 is substantially similar to strap system 14 and other strap systems described herein, except as otherwise described and depicted. Clip 562 and receiver 566 are substantially similar to clip 546 and receiver 542, except for the differences described and depicted herein. Clip 562 includes coupler 564, to which a strap or other object is coupled. Clip 562 rotates with respect to receiver 566 about axis 568 over range 570. In one embodiment, range 570 is between 30 and 60 degrees, and more specifically between 40 and 50 degrees, and more specifically range 570 is 45 degrees. In use, back strap 572 is coupled to clip 562, and receiver 566 is coupled to shell 20.

The ability of clip 562 to rotate with respect to receiver 566 permits back strap 572 to maintain a flat interface or nearly flat interface against the back of the user's neck. As a result, back strap 572 is less likely to be uncomfortable for the user (e.g., by chaffing and/or digging into the user's skin).

Referring back to FIGS. 23-85, it is contemplated herein that the strap systems described above for which the side straps are adjustable may be reconfigured so that the back straps are similarly adjustable. Similarly, it is contemplated herein that the strap systems described above for which the back straps are adjustable may be reconfigured so that the side straps are similarly adjustable.

Turning to FIGS. 86-87, various aspects of coupling and decoupling the strap system 82 and crown 84 are shown. Strap system 82 is substantially similar to the other strap systems described herein except for the differences described and depicted herein. Crown 84 is substantially similar to the other crowns described herein except for the differences described and depicted herein. Crown 84 includes one or more recesses or apertures to facilitate a user accessing front clip 52 (FIG. 86) and back clip 54 (FIG. 87).

Turning to FIGS. 88-95, various aspects of clips that couple to an exterior surface of outer shell 90 are shown. Outer shell 90 is substantially the same as outer shell 20 except for the differences described and depicted herein. Clip 900 is secured to an aperture 30 on a side portion of outer shell 90. Clip 900 includes a base 902 and actuating arm 904. Arm 904 is biased towards base 902. Arm 904 and base 902 collectively define aperture 906, into which objects (e.g., pencils, safety glasses) can be secured to clip 900.

Turning to FIGS. 89-90, various aspects of clips 920 and 940 are shown. Clip 920 and clip 940 are substantially similar to clip 900 except for the differences described and depicted herein.

Turning to FIGS. 91-95, various aspects of clip 960 are shown. Clip 960 is substantially similar to clip 900, clip 920 and clip 940 except for the differences described and depicted herein. Clip 960 includes lower arm 962, which is biased towards base 970. Lower arm 962 and base 970 collectively define lower aperture 964. Clip 960 also includes upper arm 966, which is biased towards base 970. Upper arm 966 and base 970 collectively define upper aperture 968.

In use, lower aperture 964 receives a pen (best shown FIG. 92). Pen can be inserted into lower aperture 964 via pushing the pen against the bottom of lower arm 962 until lower arm 962 is biased away from base 970 and pen is inserted. Alternatively, pen can be inserted into lower aperture 964 by sliding the pen longitudinally into the lower aperture 964. Similarly, a carpenter's pencil can also be inserted into lower aperture (FIG. 93), as can safety glasses (FIG. 95). Similarly, a small diameter pencil may be inserted into upper aperture 968 (FIG. 95).

Turning to FIGS. 96-97, various aspects of crown 170 are shown. Crown 170 is substantially similar to crown 100 except for the differences described and depicted herein. Lower portion 178 of middle frame 172 extends distance 174 further from the user's head than upper portion 176 of middle frame 172. Described another way, middle frame 172 defines a recess 180, into which objects can be inserted without being biased against the user's head, thereby reducing discomfort to the user. For example, arms of safety glasses can be inserted within recess above the user's ears, the safety glass arms are not biased by middle frame 172 against the user's head (although the safety glass arms themselves may bias towards the user's head to secure the safety glasses to the user's head).

Referring to FIGS. 98-103, various aspects of a system for coupling safety headwear, shown as coupling system 600, are shown. In various embodiments, coupling system 600 includes strap system 610, clip 612, receiver 614, receiver 616, helmet 620, cushion 630, and suspension system 640.
